JOHN T. PARRISH, OF DULUTH, MINNESOTA.

GEAR-CASING AND BAND-OPERATING DEVICE FOR AUTOMOBILES.

Application filed ctober 20, 1919.

- citizen of the United States, residing at Duluth, in the county of St. Louis and State of Minnesota, have invented certain new and useful Improvements in Gear-Casing and Band-Operating Devices for Automobiles, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to an improved form of transmission band operating devices and housing thereof for Ford automobiles.

The principal object of the invention is to provide a more convenient and accessible mechanism of this character than heretofore em loyed.

)ther objects and advantages of the peculiar construction will appear in the further description of the invention.

In the accompanying drawings forming part of this application and in which like reference characters indicate like arts:

Figure 1 is a broken top plan view of one of my improved gear housings with the band supporting and operating shafts in section.

Fig. 2 is a bottom plan view of a cover for the housing. 7

Fig. 3 is a side elevation of one of the cover holding devices showing a portion of the cover and housing in section.

Fig. 4 is a side elevation of the assembled housing showing the pedals in elevation and a portion of the housing in section.

Fig. 5 is a transverse sectional view through the casing and centrally of one of the band supporting and controlling shafts.

Fig. 6 is an end elevation of one of the thrust or cam nuts carried by the shafts.

Fig. 7 of one of the locking nuts carried by the shafts.

Fig. 8 is an elevation of a portion of one of the shafts upon which the locking nut is coiliperatively engaged, and

ig. 9 is a bro en perspective view of the trip sleeve.

1 represents the lower half of a Ford transmission gear case or housing and u on which my improved upper section 2 is b0 ted in the ordinary manner.

The section 2 is somewhat wider than that commonly used and is provided with a substantially rectangularly shaped opening or comprises an elevation and section Specification of Letters Patent.

hatch over the major portion of which is provided as a closure therefor, the cover 3. The opening in the section 2 is of a greater width than the diameter of the bands to permit of same being readily removed or applied through this section while in place.

Upon one side of the section 2 is formed an enlargement 4 providing a chamber 5 for the reception of the generator commonly used on such machines.

The cover 3 is provided with a rectangularly shaped groove 6 adjacent the edge of its under side, and which groove fits over the similarly shaped projection 7 about the fdge; of the opening or hatch in the see- .lOl'l A suitable gasket or flat packing indicated at 8 may be used within the groove 6 as desired.

Adjacent the upper and lower edges of the cover and pivotally carried thereby are two locking devices the handles of which are indicated at 9-9. These handles are each rigidly fixed to a stem 10 which carries upon its lower end a spirally shaped locking nut 11 having an annular rib or flange 12 upon which engages an arcuately shaped channel l3 in the under side edges of the opening Within the section 2. These nuts 11 are formed with a portion thereof removed as indicated at 14 whereby they may be turned to such position as to permit entrance into the opening or hatch without engaging the edges thereof as clearly seen in Fig. 2 of the drawings.

\Vhen the cover is applied with the nuts in this position they may be turned to locked engagement with the under side of the edges of the opening and given any degree of pressure desired, for holding the cover in place, such locked position being illustrated in Figs. 3 and 4. In this manner a convenient holding device is provided for the cover and which obviates the use of bolts or nuts as is evident.

The band brakes 15 and their sup ortin lugs 16 employed. are those common y use on such cars but -the supporting and controlling shafts are difierent in that they each comprise a pluralit of cooperative sections, and I shall procee to describe one of such sectional shafts for the better comprehension upon w ch the pedal 18 is rigidly fixed and extends through tlw shle wall of thn housin;! section and to but a short distance heyontl the innvr wall of tl'w housing where it is bifurcated, aml is pirntally attached to the reduced portion 19 ot' the intnrmetliatn section 19 of the shaft.

It 18 well known in the art that t e lugs have produced a nove form of housin section in combination with a separable and adjusting'shaft which will permit ofthe removal or applic tion of the band brakes with. the least p(?& and various mo ifioations from the embodiment here shown and within the scope of the ap ended claims may be resorted to withou' departing from the spirit of the invention.

; Having thus described my invention what I claim and desire to secure by Letters. Patent is: j

1. In a power transmission mechanism of the type, wherein a plurality of bands are used to brake certain parts of said mechapism, of an upper section therefor having an opening therein greater in extent than the diameter of the transmission bands and a band adjusting shaft therein pivotally adjustable through the opening to permit of the bands being removed from the housing in their entirety. 1

2. In a power transmission mechanism of the type wherein a plurality of bands are used to brake certain parts of said mechanism, a. gear housing of the character described having an opening therein greater in transverse dimension than the diameter of the gear bands,'a band adjusting shaft pivotally mounted withinthe housing and capable of bein raised pivotallythrough the o ening, an, anlosute for said opening.

3. n a power transmission mechanismpf the iype wherein a plurality of bands are used to brake certain parts of said mechanism, the combination with a transmission gear housing of the character described having bearings in the op ositesides thereof for the transmission band shafts; of each shaft comprising a plurality of adjustable sections the intermediate one of which is pivotally supported, substantially as and for the purpose described.

4. In a power transmission mechanism of the type wherein a plurality of bands are ible work and-annoyance,

substantially as described.

used to brake certain parts of said mechanism, the combination with a transmission gear housing of the character described havmg an opemn therein T greater width than the normal iameter of the transmission bands, of band controlling shafts journaled within the housing and pivotally adjustable throu h the opening and means where by the rocging of the shafts will control the bands without reciprocating the shafts.

5.

6. In a power transmission mechanism of the, type wherein a plurality of bands are used to brake certain parts of said mechanism, the combination with a transmission gear housing of the character described of sectional shafts for operating the transmission bands, a rec-i rocable thrust collar car ried by each sha within the housing and means whereby when each shaft is rotated the thrust collars will be reci rocated upon the shafts and operate the en s of the bands 7. 'In a power'transmission mechanism of the type wherein a plurality of bands are used to brake certain parts of said mechanism, the combination with a housing for the transmission gear of an automobile having an upper opening therein of greater widt than the normal' diameter of the transmission bands, sectionalband 0 rating shafts within the housing removab e from' the interior thereof, means externally of the housing for adjusting the operating shafts and a closure for the openin in the housing.
